Los Angeles County lost 13,241 residents in the past year, the fourth-biggest drop among the nation’s 100 most-populous counties.

Newly released U.S. Bureau Census population stats show the county had 10.11 million residents as of July 1, 2018 — still No. 1 among the nation’s 100 largest counties. Only Illinois’ Cook County (Chicago) and New York’s Kings (Brooklyn) and Queens counties lost more folks in the year. On a percentage basis, that population dip — equal to 0.13% — ranked the county No. 87 among the Top 100.

It’s the second straight decline as in 2017 Los Angeles County lost 1,781 people — or a 0.02% loss. From 2010 to 2018, the county’s population grew at a 35,386 annual pace, No. 4 among the 100.

My trusty spreadsheet put this population change into some perspective while noting population growth has cooled regionally and nationwide …
